WITNESSES S FATE DAMPERr-REGULATOR- Application filed February 11, 1915.

To all whom it may concern:

Be it known that I, HUGO MUNZER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Damper-Regulators, of which the following is a specification.

The object of this invention is to provide a damper regulator, of the class operated by the action of gravity on a body of liquid driven from a steam boiler or the like into a suitable receptacle by pressure in the boiler, that shall be simple and inexpensive in construction, and at the same time reliable in operation, quick in responding as well as sensitive to fluctuations of pressure in the boiler and substantially proof against getting out of order.

In the accompanying drawing, Figure 1 is a side elevation of a steam heating apparatus provided with my improved damper regulating means; Fig. 2 is a rear elevation of the regulating means, showing the smoke pipe partly broken away; and, .Fig. 3 is a sectional detail of the regulating means.

Referring to Figs. 1, 2 and 3, a in the drawings is the furnace of a steam heating apparatus including a boiler Z), the water level in which is indicated by the dotted line 0; (Z is the smoke pipe of the heating apparatus and c a damper of a well known type supported in the smoke pipe in the way to be explained.

From a point suitably below the level 0 there leads from the boiler the pipe f, the upwardly extending end of which is equipped with a suitable elbow g.

In the threaded nipple h projecting laterally from the elbow is journaled the end of a horizontal pipe 2' provided with a collar 7' seating in a rabbet 7c in the nipple. This pipe 2' turns freely in the elbow on its own longitudinal axis, and to render the oint between the parts watertight and hold the pipe in place I provide a union Z, which is screwed onto the nipple, and packing m interposed between the union and the collar 7', the union may be secured against rotation by the lock-nut at. Any other form of gland may of course be employed.

The pipe 2' is closed at its free end by the cap 0. In the construction shown in Figs. 1, 2 and 3 said pipe has bearings in the Specification of Letters Patent.

smoke pipe d and to it is secured the damper 6.

Connected with the pipe 2', as by the T p, is a pipe 9 having its free end portion 1" bent off in a direction more or less at right angles to the pipe 2'. Attached to the free end of the pipe Q--7", so that said pipe discharges thereinto, is a liquid receptacle 8 having a suitable check valve t of the kind adapted to allow air to pass but not liquid, especially if heated, being a type of valve commonly used on steam radiators. On the free end of the pipe ;0 there is fixed an arm at which carries a weight o.

The system f, q, r, 3 includes a liquid receiving arm (q1', s) which is freely movable on a horizontal axis, so that when the pressure in the boiler drives the liquid into the system the arm becoming weighted by the liquid falls and moves the damper toward the closing position, and when the pressure thereupon diminishes and the water in the system recedes toward the boiler, the arm, being lightened, rises, and permits the weighted arm at to return the damper toward the open position.

Having thus fullydescribed my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, a heating apparatus having a furnace, a boiler and a damper, and a liquid receiving system connected with the boiler below and projecting above the liquid level therein and having a liquid receiving arm pivoted on a horizontal axis, the damper being fixed to the axial portion of said arm to turn therewith.

2. In combination, a heating apparatus having a furnace, a boiler, a smoke pipe and a damper in the smoke pipe, a horizontal rotary pipe, the damper being fixed to and adapted to turn with said rotary pipe, a liquid receiving means projecting radially from and communicating with the rotary pipe, and another pipe communicating with the rotary pipe and rigidly connected with the boiler below the liquid lever therein, the

rotary pipe being journaled in the last- Gopies of this patent may be obtained for five cents each, by addressing the Commissioner 0t Ratents. Washington, I). 0.
